I think if you are looking at talent in the respective positions, maybe its close in value? What i hear about Zegras is that he "may" have attitude issues, but it all sounds like heresay to me - like a bunch of oldschoolers saying the kid is too cocky because he is flashy with his Michigan style goals.
That being said, It doesnt seem clear to me that Zegras is valued by all as a C, and Guhle's attitude is beyond question. I also think it is harder to find good D than good forwards. I'd actually like to get Zegras in mtl, but not at the price of what may be our best DFD in years to come. There are plenty of other prospects to start a conversation from without touching on our known values IMO.
